Title: Encapsulation of particles by liquid-liquid phase separation
IPC: B01J13/10
Filed: 1959-10-28
Abstract: Capsules produced by a liquid-liquid phase separation technique (see Group VI) and having a mantle composed of or comprising a polysaccharide are hardened by irradiation with beta-, gamma- or X-rays, e.g. by irradiating a shallow aqueous suspension of the capsules.  Polysaccharides specifically mentioned are acecia, pectin, sodium alginate, sodium carboxy methyl-cellulose, starch-, amylose- and celluloseacetate phthalates.  Specifications 751,600, 911,483, 929,402, 929,408 and 929,409 are referred to.ALSO:In processes for the production of capsules by liquid-liquid phase separation, the capsule walls are hardened and their permeability decreased by exposure to beta-rays, gamma-rays or X-rays e.g. as a shallow layer of a suspension of the capsules in water.  The capsule walls may be composed of various polymeric materials, e.g. one or more gelable hydrophilic colloids, e.g. gelatine, albumin, fibrinogen, casein, agar, sodium oleate, pectin and ichthyocolla alone or in combination with other polymeric materials of opposite charge, e.g. gum acacia, sodium carboxy-methylcellulose, sodium alginate, cellulose-, starch- or amylose-acetate phthalate and linear macromolecular synthetic polymers, e.g. styrene-maleic acid and styrene-maleic acid amide copolymers, sulphonated polystyrenes, polymethacrylic acid and methyl vinyl ether-maleic acid copolymers.  Such polymers may also be used alone.  The phase separation process may be any such known process and the encapsulated material may be lipophilic or hydrophilic solids or liquids including oil-in-hydrophilic liquid and hydrophilic liquid-in-oil emulsions and may comprise ingredients which render the capsules useful in the manufacture of record transfer materials, medicaments, and food additives. Specific examples include an oil-in-aqueous suspension of caffeine emulsion encapsulated in styrene-maleic acid copolymer, mercuric oxide-glyceryl monostearate mixture encapsulated in gelatine/acacia and aqueous chloral hydrate solution-in-mineral oil emulsion encapsulated in styrene-maleic acid copolymer, beta-ray irradiation being used in each case. Specifications 751,600, 911,483, 929,402, 929,408 and 929,409 are referred to.

Title: Stable pure fluid amplifiers
IPC: H01B3/04
Filed: 1963-09-18
Abstract: 1,031,737. Fluid amplifiers. CORNING GLASS WORKS. Sept. 18,1963 [Sept. 26,1962], No. 36762/63. Heading G3H. A fin or aerofoil 20 is provided in at least one outlet of a pure fluid amplifier for stabilization of flow. As shown, power fluid, e.g. air, issuing from a nozzle 11 normally discharges to an outlet 16 but can be deflected to either of two other outlets 15, 17 by flow from control nozzles 13, 14, one of which carries a reference signal. Thus, when a monitored signal equals the reference signal the power flow is to the outlet 16 but when it is above or below the reference signal the power flow is directed to one of the outlets 15, 17. The aerofoil 20, which may be changed in shape or position to alter the sensitivity of the device, maintains the discharge to the outlet 16 despite small variations in the control signals. The walls 25, 27 are so shaped that flow to the outlets 15, 17 is stabilized by by boundary layer action, but these walls may be vented to atmosphere to prevent such stabilization. Modifications are described in which an aerofoil is situated in each outlet of devices having two and five outlets.

Abstract: 1344376 Delivering or feeding sheets RODER & SPENGLER oHG 6 Aug 1971 [10 Aug 1970 1 March 1971 29 March 1971] 36973/71 Heading B8R Delivering sheets.-Sheets carried on a belt 14, Fig. 2, are conveyed over a stacking table 3 by engagement between transfer means comprising a group of rods 9 carried on continuously driven chains 7 and a plurality of staggered pairs of belts 24-28 driven round pairs of rollers 29-35. When a sheet 23 is fully over the table, the belts 24-28 are stopped by disengaging magnetic clutches, so that, owing to higher friction between the sheet and the belts than the sheet and the rods, the sheet stops, while the rods move away from underneath it, Fig. 4, to allow the sheet to drop on to the table. The front end of a next group of rods 9 is then in position to receive the next sheet. In another form, Figs. 8 and 9, the transfer means comprises a belt 121 passing over a roller 123 adjacent a delivery conveyer 134, over a roller 124 adjacent a co-operating belt 135, and over a plurality of carrier rollers 113- 117 connected together by a flexible cable 119, the roller 113 being mounted on a carriage 119 which reciprocates in a guide slot 110 as the carriage alternately engages the upper and lower runs of a chain drive 107. Spring-urged rollers 128, 130 compensate for the movement of the roller 113. Sheets delivered from the conveyer 134 are carried over a stacking table 104 by the belt 121 when it passes over the rollers 113-117, and when the rollers are retracted to the position of Fig. 1, the sheet is deposited on a stack 101. The table is lowered by chains 102 as the stack forms. In another form, Fig. 11, the transfer belt 221 passes over guide rollers 213, 230 jounalled on guide chains 207, 234, the roller 213 reciprocating over the stacking table 204 and the roller 230 moving to compensate, whereby the sheets 203 are drawn over the table 206 and deposited thereon. Feeding sheets.-Any of the forms described may be modified for separating sheets from the top of a pile on the table, by reversing the drive of all the conveyers and of the table, and providing above the left end of the table a plurality of vertically slidable suction separators which grip the left end of a sheet and raise it, whereupon the rods 9 (or rollers 13-17 or roller 213) move under the sheet to separate it from the pile, and it is then forwarded by means such as the belts 24-28 to the belt 14 or other forwarding means.

Abstract: 849,264. Circuits employing bi-stable magnetic elements. BURROUGHS CORPORATION. Dec. 12, 1956, No. 37994/56. Class 40 (9). [Also in Group XXXV] A magnetic storage element comprises a plurality of conductors 11, 12, 13, linking a core 16 formed by winding a strip of magnetic material with a square hysteresis loop around the conductors. The conductors may be ordinary enamel-coated or plastic-coated insulated wire, or may be platinum insulated with vitreous material to permit the magnetic strip to be annealed after winding. The magnetic strip may be iron containing 5% silicon or Permalloy. Storage arrays.-A storage array is formed by a plurality of elements connected between terminal areas 42, 43, 44, etched on an insulating base 41 by printed circuit technique. As shown in Fig. 4, a three-by-three array has column read-in conductors 12, row read-in conductors 13, and a read-out conductor 11. Each conductor may be connected to adjacent terminal areas, or a row or column may be threaded by a one long conductor as for example the conductor 12, 45, 46, 51 in the first column. Alternatively the areas 42, 43, 44 may be replaced by soldering lugs. In a 16 x 16 array the rows are divided into two sets of eight, and the readout conductors instead of being diagonally connected are arranged vertically alongside the column read in conductors, and connections are made to minimize noise current. In manufacture a number of cores are wound at intervals along parallel arranged conductors and cuts are made where necessary for connections (Fig. 5). Fig. 4 shows in block diagram form circuit arrangements for use with the array, wherein an address selecting device 76 determines the effective positions of switches 63, 71 in the switching circuits 61, 68 and the timing read-in circuits 77 control pulses from pulsing circuits 62, 69 to the selected core. Read-out gating circuits 83 and utilization device 82 are included and gated open through conductors 83 by the timing unit 77 during a read-out period, and read-out pulses are supplied from pulsing circuits, 62, 69. Conventional circuit arrangements (not shown) may be provided to restore a switched core and so make the reading out non-destructive.
